The benefits both personally and "to the cause" FAR outweigh the negatives.
Personal, well, you don't get hassled by cops as much. 'Nuff said.
In the broader sense, the state knows how many people have such permits. Which gives three benefits:
1) The state knows how many "hard core gunnies" would get screwed if they reversed course.
2) Better yet, "stats guys" like John Lott, David Kopel and the like get to come along and sort out how many people are committed to self defense, during what time periods, and what effect that had on crime rates.
3) The general public gets to see that mass carry does NOT cause problems. This tends to get reported in the media - see also
http://www.equalccw.com/ccweffects.html for a collection of same. So when some grabber politician runs for office and says "guns are eeeeevil", the population of the shall-issue states gets to go "what the hell is he talking about?"
Make no mistake: long term, I'd rather see Vermont/Alaska type carry than shall-issue. HOWEVER, I think the current period of predominantly shall-issue rules will be long-term beneficial in establishing widespread self defense as a net benefit.
And of all the state "experiments" to date, I predict the one that will be the most long-term valuable will be Michigan.
Do y'all understand how violent Detroit is? A couple years back, somebody calculated that if the US were to simply make a gift of Wayne County (where Detroit is) to Canada, the relative per-capita murder rates of Canada and the US would *equalize*
. Sigh. So they've finally gone shall-issue - Detroit is now the ONLY major inner-city hellhole with shall-issue...and last year, for the first time in 40 years, Michigan's overall violent crime rate was lower than Ohio's.
THAT shook the hell out of the Ohio legislature and was a major factor in Ohio's recent shall-issue reform.
Upshot: keep a close eye on Detroit's violence/murder levels over the next 5 to 10 years, pending of course reforms in even worse areas like WashDC and Chicago.
Detroit is going to be our main proving ground.
